Implementing Multicast Routing between vSphere DVS and DellEMC Networking

vSphere DVS supports IGMP & MLD Snooping functionality which helps in precise and efficient way of handling multicast forwarding by listening to IGMP messages to/from the Virtual machines. The vSphere DVS supports IGMPv1, IGMPv2 and IGMPv3 for IPv4 multicast group addresses & MLDv1 and MLDv2 for IPv6 multicast group addresses. When IGMP Snooping is enabled…… Continue reading Implementing Multicast Routing between vSphere DVS and DellEMC Networking

NSX-T Tier0 Inter-SR iBGP ECMP Explained

NSX-T introduced Inter-SR iBGP routing between the SR Components of the T0 Gateway in version 2.4. This feature helps to tolerate an asymmetric failure of the SR component on the Edge node (Eg: uplink failures) by routing the internal traffic reaching to it (from the T0 DR Component) over to the iBGP inter-SR link to…… Continue reading NSX-T Tier0 Inter-SR iBGP ECMP Explained

NSX-T Single N-VDS Multi-TEP Baremetal Edges Deployment and Configuration

With the release of version 2.4, NSX-T now supports a Single N-VDS and Multi-TEP Baremetal Edge Configuration. With a Multi-TEP design, we could achieve redundancy when a TEP uplink fails instead of failing over to the Stand-by Edge node. This is the recommended configuration when we have two or more DPDK interfaces for the Baremetal…… Continue reading NSX-T Single N-VDS Multi-TEP Baremetal Edges Deployment and Configuration

NSX-T Tier0 AS-Multipath-Relax Explained

NSX-T introduced support for BGP AS-Multipath-Relax from version 2.4 which helps to achieve ECMP accross eBGP Leaf Switch Peers that differ in ASN path attribute values, but have the same AS-path length. As I mentioned in my previous article on ECMP routing, lets revisit the requirements to be met to achieve ECMP between the T0…… Continue reading NSX-T Tier0 AS-Multipath-Relax Explained

NSX-T Tier0 ECMP Architecture and Routing Explained

NSX-T Tier0 Gateway supports ECMP in BGP routing with the Leaf Switches which helps utilizing all the Edge Uplinks for Egress and Ingress traffic. ECMP mode is available only when the Tier0 Gateway is deployed in Active-Active mode. ECMP is applied at three levels: T0 DR-SR ECMP : Between the T0 DR component and T0…… Continue reading NSX-T Tier0 ECMP Architecture and Routing Explained

NSX-T Tier0 Inter-SR Routing Explained

Inter-SR Routing is an iBGP peering feature between the SR Components of the Tier 0 Gateway deployed in Active-Active mode. This feature helps to tolerate an asymmetric failure of the SR component on the Edge node by routing the internal traffic reaching to it over the iBGP inter-SR link to the SR component on the…… Continue reading NSX-T Tier0 Inter-SR Routing Explained

Deploying and Configuring NSX-T Edges on N-VDS Networking

NSX-T Edges have flexible deployment options based on the host networking that is used. We can deploy NSX-T Edges on Distributed vSwitches (which is managed by vCenter Server) or on host N-VDS (which is managed by NSX-T). NSX-T Edges deployment and configuration on DvSwitches has been covered in my previous post, you can find it…… Continue reading Deploying and Configuring NSX-T Edges on N-VDS Networking
